There is no pressing need to start building 1.5 bytecode as long as an 
application compiles with 1.4 but if an application uses 1.5 features we 
   will not be backporting the code to work with 1.4 which would be 
required for you to be able to run applications with 1.4. If you want to 
maintain such ebuilds we can give you access to an overlay where you can 
keep 1.4 compatible ebuilds around. The Java team doesn't have that much 
man power and it's better used towards other things than keeping 1.4 
functional with our hundreds of packages.

Petteri
